Responding to a brief impromptu discussion on the issue, Mukherjee, who is the Leader of the House, said Trivedi has sent his resignation to the Prime Minister last evening and it was being considered.

"The Prime Minister has received last night the resignation letter from Dinesh Trivedi. It is under consideration of the Prime Minister," he said.

He also said as per the procedure the letter has to be forwarded to the President, who then takes a decision as per the advice of the Prime Minister.

"As soon as a decision will be taken, the House will be informed of it," he said.

To Opposition leaders' claims that the House had been kept in the dark, Mukherjee said on Friday the Prime Minister had received a communication from Trinamool Congress chairperson Mamata Banerjee and Trivedi had not resigned then.

Mukherjee pointed out that after the presentation of the Union Budget the Lok Sabha was adjourned till Monday.

He said the government has informed the House of the developments at the earliest opportunity available.
